Hi Isabella😊
Thank you for your question✨
Yes, the COSRX Full Fit Propolis Synergy Toner can be combined with vitamin C, and they usually work well together since the toner is mild and hydrating.
✅ Tips for use:
-Use vitamin C after cleansing and before or after the toner (test what works best for your skin).
-Feel free to apply in the morning and finish with sunscreen.
If you have sensitive skin: start carefully, patch test on a small area first or e.g. every other day, and avoid combining with other active ingredients on the same day (like AHA/BHA/retinol).
The toner can help soothe and hydrate the skin, making vitamin C easier to tolerate. All skin is unique, so try and see what works for your skin.
Hope the answer can be helpful and that you have a super nice day🌞
